groups of professional people do not easily disregard the process of disciplined thinking, with full consideration of all points before making any suggestion — brainstorming demands a "free-wheeling" mental technique, where everything is considered possible:
• Create a comfortable, relaxed atmosphere, with no possible interruptions or telephone calls.
• Select a good leader and a recorder.
• Keep the group to a manageable size (say eight maximum).
• Clearly define the problem, before starting.
• Write down every idea, with no discussions or dissension.
• Strive for a large collection of ideas.
• Ensure that everyone makes a contribution.
• Walk away from all the ideas at the end of the session, evaluate and discuss at the next one (or two) sessions.
